Kksuns and Illusive are so right! Parakeets take a lot of time and comittment, as does any other pet that you decide to adopt! It does sound like you have a lot on your plate. Maybe you should take into consideration that you may be too busy for a parakeet right now. At my local animal rescue league, they generally have reasons why the animal was surrendered. I see this reason a lot of parakeets and other birds: NOT ENOUGH TIME.

Trust me, I don't think you want to be one of those people.

Good luck! : )
